The HTML MessageBox allows you to make your Windows application's
message boxes more readable and usable by allowing
you to set a larger default font, then use simple HTML to add
emphasis such as boldface to the most important points in
longer messages.

Worried that your users aren't reading your application's message boxes
because the font's too small, or they are too long?
Wish Microsoft gave you a way to add some emphasis to the most important
points in your message?
Use the HTML MessageBox, and these concerns go away!

The HTML MessageBox works on Windows 2000, XP, Vista, 2003 or higher, and
features all-Unicode functions. It comes with interfaces or sample code for
the Win32 API (e.g. for C/C++), COM, .NET, and PowerBuilder, so it should be
callable from virtually any Windows application (other than web applications).

Some users might find this page by searching for "Rich Text
MessageBox", because rich text generically refers to the ability
to add fonts, boldface etc. to your text. The HTML MessageBox uses simple
HTML, rather than the much more complex and verbose RTF, but it serves the
same purposes. See the Why HTML MessageBox?
page for details about an actual RTF MessageBox that is available elsewhere,
if for some reason you would actually prefer that!

Another thing people might be searching for is "Bold MsgBox" or words to that effect, because the MessageBox function is called MsgBox in VB.
